Abstract (en)
A radio base station apparatus includes an intermittence determination unit which controls to be transmitted a reference signal over a first transmission period in a second cell, when the intermittence determination unit receives a first message including a quality of a first cell subordinate to the radio base station or a quality of the second cell subordinate to the radio base station apparatus or another radio base station apparatus, measured by the terminal apparatus in the first cell, and when a reference signal is transmitted over a second transmission period shorter than a first transmission period in the second cell; and a handover determination unit which receives a second message including the quality of the second cell measured by the terminal apparatus in the first cell based on the reference signal transmitted over the first transmission period and determines a handover destination based on the quality of the second cell.
